GEORGE HUNZINGER, OF NEW YORK, N. Y., ASSIGNOR TD HUNZINGER & SON,

OF NEW YORK, N. Y., A FIRM.

CHAIR.

Application filed June 22, 1814..

T 0 all whom it may concern Be it known that I, GEORGE HUNZINGER, acitizen of the United States, residing at the borough of Manhattan,city, county, and State of New York, have invented an in provement inChairs, of which the following is a specification.

My invention relates to a chair, and particularly to that class ofchairs in which there are suitably connected members, one of which isadapted to rock upon the other and which may be locked in positionrelatively to the other, so as to provide an ordinary chair, a rockingchair or a reclining chair, for which reason the chair made inaccordance with my invention may be called a three-positioned chair.

In carrying out my invention, the chair inade in accordance therewithpreferably comprises a base and a seat frame member suitably connectedtherewith, so as to rock thereon, together with means placed in andoperated from one side only of the chair for locking the seat frame inposition to make the use of the same that of an ordinary chair, and alsofor locking the seatframe in such a position as to make the use of thechair that of a reclining chair, as will be hereinafter moreparticularly described.

In the drawing, Figure 1 is an elevation and partial cross section ofthe chair illustrating my present invention. Fig. 2 is a sectional planon line 2, 2, Fig. 1, and Fig. 3 is a cross section taken through oneside of the chair on the line 3, 3, Fig. 1, and Fig. 42 is a partialcross section taken through the side of the chair on the line 1, 1, Fig.1.

As will be seen by reference to the drawing, the chair constructed inaccordance with my invention preferably comprises a base member,including front legs 10 and rear legs 11 suitably connected by sidemembers 12, between which cross members 13 and 1% extend. Suitablysecured to the inner face of one of the side members 12, and extendingupwardly therefrom, is a lock plate 15, in which there is a recess 16,the purpose of which will hereinafter appear. My improved chair alsoincludes a seat frame member preferably comprising a front board 17,sides 18, and cross members 19 and 20, the former being placedimmediately behind the front board 17, and the latter extending betweenthe sides 18 at the rear thereof. This frame is suitably fitted orSpecification of Letters Patent.

Serial No. 848,423.

upholstered with a cushion seat 21, and furthermore, the seat framemember also preferably includes a back 22 suitably upholstered orprovided with a cushion and arms 21.

One of the sides 18, preferably that on i ri 'hthand side of the chair,is provided with an aperture adapted to receive a pin 2 Exteriorly ofthis side 18 the pin is provided with a head 26, and in a suitableposition extending lon itudinally of the pin there is a slot or recess27 therein. The said side member 18 is also provided with a peg 28adapted to project into the recess into which the pin is fitted, and toextend into the slot in the said pin to limit and determine the extentof its movement.

Attention is here directed to the fact that the chair seat frame memberis preferably provided at its forward corners with upright members 29,which, when the chair is in the position shown in Fig. 1, formsubstantial continuations of the front legs 10, so as to give the chairthe appearance of an ordinary one, and between the bottom surfaces ofthe upright members 29 and the top surfaces of the legs 10, I may employstops or buffers 30, which are preferably secured in the upright members29, and as will be understood, prevent unnecessary strain uponv theparts of the chair in bringing the same to the position as shown in Fig.1.

As clearly indicated in Fig. 1, the lower edges of the sides 18 arecurved and adapted to rest upon the upper edges of the sides 12, so thatunder certain circumstances, the chair seat frame member may rock uponthe base member, and these parts are suitably connected by any yieldingmeans known for this purpose, in this art. As shown in the drawing, andas seen in Fig. 2, for this purpose, I employ sets of brackets 32 and33. The members of the former set are connected respectively to theunder and upper surfaces of the cross members 19 and 13, while themembers of the other set are connected respectively to the under andupper surfaces of the cross members 20 and 14.

Associated with the brackets 33, there are inks 3 1 and 35, preferablybifurcated at both ends, and at corresponding ends pivotally connectedto pins 36, journaled in the brackets 33, while at their opposite endsthese links 34 and 35 are pivotally connected to a pin 37. Similarly, atthe front of the chair there are links 38 and 39, also bifurcated atconnected to a pin 41. The pins 37- and 41 are connected by springs 42and 43, which at their respective ends are secured to the correspondingends of the pins 37 and 41 and extend between the same.

In a suitable position, the side member 12v on the right-hand side ofthe chair, is provided with a slot 45, through whlch a screw '44 passesand is turned down or otherwise suitably secured in the correspondingside 18 of the chair frame member, the head 46 of the screw 44 being incontact with the under surface of the said member 12 when the parts ofthechair are in the dotted line positions indicated in Fig. 1, for thepurpose which will hereinafter appearr As will be apparent from theforegoing description, the seat frame member of the chair may be lockedinthe position as shown in full lines in Fig. 1, by causing the pin 25to assume the position indicated in Fig. 3, in which its inner endlieswithin the recess 16, in the lockplate 15. It will also be apparent thatby withdrawing the pin 25 so that its inner end will clear the lockplate 15, the seat frame member of the chair is free to rock upon thebase, being yieldingly secured in position thereon by means of thesprings, links and brackets, as hereinbefore described. It will stillfurther be apparent that by tilting the seat frame member to the Yposition shown in dotted lines in Fig. 1, and

moving the pin inwardly sothat the same will rest: against the top ofthe lock plate 15, the parts will be maintained in the position in whichthe chair is a reclining one. Further, inasmuch as, in this position theseat frame member is merely supported at one point and at one sidethereof, I also employ the screw 44 for preventing the seat-frame memberfrom tipping forward on the opposite forwardcorner thereof, this beingprevented, as will be apparent, by the engagement of the head of thescrew with the under surfaceofthe side member 12.

I claim as my invention:

1. A chair comprising a base, a lock plate secured to and extendingupwardly from,

Copies of this patent may be obtained for one side of the base, a seatframe adapted to rock upon the said base, means for yieldinglyconnecting theseat frame and b'ase,'a device passing through the side ofthe seat frame and adapted to engage with the said lock plate when theseat frame is in a for ward position to lock the parts together and makethe use of the chair that of an ordinary one, the said device'being alsoadapted to rest upon the said lock plate when the seat frame is ina'rearward position to make the chair a reclining one. I

2. A chair comprising a base, a lock plate secured to and extendingupwardly from one side of the base, a seat frame adapted the said lockplate when the seat frame is in a rearward position to make the chair areclining one.

3. A chair comprising a base, a lock plate secured to and extendingupwardly from one side of the base, a seat frame adapted to rock on thesaid base, means for yieldingly connecting the said seat frame to thebase, a pin passing through the side of the said seat frame and adaptedto enter a slot provided for this purpose in the said lock plate, whenthe seat frame is in a forward position to lock the parts together-andmake the use of the chair that of an ordinary one and also to rest uponthe top of the said lock plate when the'seat frame is in a rearwardposition to make the chair a reclining one, and means when the seatframe is in its reclining position for preventing the same from tilt ingforward in front at the side opposite to that on which it is supportedby the-said in.
